Accuracy analysis of fixed voltage setpoint indices for voltage stability
2010 International Conference on Power System Technology, 2010There are many voltage stability indices for voltage security assessment and calculating stable margins from operating points to voltage instability at each load bus. Among them, one type of indices based on fixed voltage setpoint is applied in practice. Previous research has proved inaccuracy of these indices with the P-V curve method. This paper aims

Line stability indices for voltage collapse prediction
2009 International Conference on Power Engineering, Energy and Electrical Drives, 2009Voltage collapse is a problem that occurs in heavily stressed systems. This paper compares the effectiveness of line stability indices in providing information about the proximity of voltage instability of a electrical power system. Line voltage stability indices can provide an accurate information of the stability condition of the lines of the system ...

Indicating and mitigating voltage collapse comparing voltage stability indicators
2012 3rd IEEE PES Innovative Smart Grid Technologies Europe (ISGT Europe), 2012Novel measures to indicate and mitigate voltage collapse in the power system are presented in this paper. The functionality of conventional and unconventional indicators and mitigating actions are tested in a case study using the IEEE Reliability Test System 1996.

A comparison of voltage stability indices
2014 IEEE 8th International Power Engineering and Optimization Conference (PEOCO2014), 2014The stressful condition of power system and high transmission losses leads to voltage security and reliability problems of system operation. If the voltage stability is not assessed and the problems occurred are not mitigated properly, cascading events may occur and this may lead to voltage collapse or blackout events.

Evaluation of some indices for voltage stability assessment
2009 IEEE Bucharest PowerTech, 2009The liberalization of the electricity markets causes power systems to work closer and closer to their limits. The online assessment of system security becomes a topic of paramount importance in control centers. In this context fast indices to quickly assess system security are fundamental in an on-line DSA session.

A Review of Voltage Stability Assessment Techniques with an Improved Voltage Stability Indicator
International Journal of Emerging Electric Power Systems, 2015Abstract A blackout can take place in entire power system or a part of the system due to extreme voltage instability (voltage collapse) that can appear abruptly. Instability prediction and continuous monitoring of the power system performance is, therefore, known exigent.

Properties of indices for voltage stability assessment
2013 8TH INTERNATIONAL SYMPOSIUM ON ADVANCED TOPICS IN ELECTRICAL ENGINEERING (ATEE), 2013The paper deals with evaluation of a power system from the view-point of voltage stability. It is concerned with the indices which are proposed as voltage collapse proximity indicators. In the existing papers, many such indices can be found. In the paper, the so-called line stability indices, defined using the static approach to the study of voltage ...

Voltage Stability Assessment Using Line Stability Indices
2018 3rd International Conference and Workshops on Recent Advances and Innovations in Engineering (ICRAIE), 2018At present, after examining the stability of the voltage we found concerns in the regular working of the power systems. It was observed that there was a lot of load in the system which lead to the concerns. It is important to run the system with minimum power loss because of increasing need of power by the humans and lack of enough power sources to ...
